What commercial roofing is, and what to ask about it

Commercial roofing covers retail, office, warehouse, church and multi-family buildings. Most of these roofs are flat or low-slope and use single-ply membranes, modified bitumen, built-up roofing or standing seam metal.

Crews, materials and warranties differ from house roofing. A company that is good on shingles may not be the right one for a membrane roof.

Signs you need it

  • Ponding water after rain on a flat roof
  • Open seams or failed flashing at rooftop units and parapets
  • Ceiling stains below drains, units or roof edges
  • A roof near the end of its warranty, with a lease or sale coming up

Ask each roofer

  • How many buildings like mine have you roofed in the last two years?
  • Do you scope the whole drainage path or only the wet spot?
  • Can you scan or core the roof to see whether the insulation is wet?
  • Who holds the membrane warranty, you or the manufacturer?

What Mankato changes about commercial roofing

The county has fewer roofing companies with payroll than most cities we cover, so a commercial job may draw few bidders. Ask early who will bid, and whether nearby companies will travel.

A large share of Mankato's housing sits outside single-family houses, so flat and low-slope roofs are common. Ask every company about its experience with your type of building, not only with houses.

A commercial roof laid before April 2026 was in place for the largest stone in the record, so ask for a roof survey and keep it with the warranty papers.

Why this page prints no city price for commercial roofs

A commercial roof is priced by the building: its area, membrane, insulation, drainage and rooftop equipment. One range per city would mislead.

Ask each company for a written scope and a price per square foot of roof, so bids can be compared line by line.
